It might be a good idea for her to go to her school guidance counselor and explain the situation. Many schools have in house psychologist who can meet with her parents and discuss her concerns. They are not allowed to diagnose, but will lead them in the right direction for help. There is so much stigma attached to mental illness, and her parents would probably be more open-minded to agree for a mental health professional to evaluate their daughter. I would also suggest she print out some literature about teens and bipolar disorder for them to look at. It was a very good thing for you to give her the info you did too.
